You are right, if multiple panels are in one group it is different, also freeing the panel
doesn’t work if you click on windows title instead one needs to double click the tab field.

And it seems behaving awkward, to be honest - at least on linux it draws only half
of the panel first and then once updated the rest. (??)

FWIW, I already had the Doc Switcher (aka Document List Panel in Preferences) on the left with some other things as well (Explorer plugin window, Explorer favorites window, Document Map). Freeing the Doc Switcher worked, but then click-dragging it and moving slowly to the left didn’t work at all. I found I that had to click-drag and slowly move up into that area from the bottom to get the phantom rectangle to appear–the one that lets you know that if you release the mouse, your floating window will doc in that spot.

double click into the window area with the Doc Switcher name

this will release it like here

slowly drag it to the left by clicking into the area as before but keep pressing the
left mouse but until you see if attaches to the side. Done.
